Bailey Bridge is a kind of prefabricated road steel bridge, which is widely used in the world.It has the characteristics of simple structure, convenient transportation, fast erection and easy decomposition.At the same time, it has the advantages of large carrying capacity, strong structural rigidity and long fatigue life.It can make up the different span of various types and various uses of temporary bridge, the emergency bridge and fixed bridge according to the actual needs, with the characteristics of less component, lightweight and low cost.
The truss of the Berry frame is made of the upper and lower string rod, vertical rod and inclined rod welding. The end of the upper and lower string rod has the Yin and Yang joint, and the connector has the truss connecting the pin hole.Truss string by two 10 groove steel (back to back) combination, on the lower string, welding more pieces of steel plate with round holes, in the upper and lower string for strengthening string and double truss bolt holes, and four bolt holes for connecting the support, two holes are for double row or multi-row truss joints, the two holes at both ends are connected between joints.
When multiple rows of trusses are used as beams or columns, the junction of the upper and lower two trusses must be reinforced with support frames.On the lower string bar, there are four beam pads, above which there are tenon to fix the position of the beam on the plane: there are two oval holes on the belly of the groove steel at the end of the string bar, for connecting the wind pull rod.The truss vertical bars are made of 8 # I-word steel, with a square hole on the lower string bar side of the vertical bar, which is used for the beam fixture to fix the beam.The truss members are 16Mn and weighs 270kg per piece.
The frame belongs to the large equipment, needs to use a large engineering, such as some projects need temporary across the river or swamp system, can use the piece of temporary steel bridge, that is, the industry often says the steel bridge, or any other place need to build temporary steel bridge or temporary support, can use the piece to do.Also known as the lane plate, is the vehicle wheel pressure bearing load-bearing structure.
In structure, it is usually connected with the beam ribs and transverse partition of the main beam, so that it can not only pass the vehicle to the main beam, but also form the cross section of the main beam, and ensure the overall function of the main beam.Bridge deck plate is generally made of reinforced concrete, and can apply transverse prestress.
